Subject: Revert "PCI: fix IDE legacy mode resources"
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=af1bff4f1d117f99ad8a88e6532baff475fb44a5;p=openwrt%2Fstaging%2Fblogic.git

Revert "PCI: fix IDE legacy mode resources"

This reverts commit fd6e732186ab522c812ab19c2c5e5befb8ec8115, which
helped up things on MIPS, but was wrong for everything else.  As Ralf
Baechle puts it:

  "It seems the whole MIPS resource managment is complicated enough (out
   of necessity) that only a few people actually grok it.  Ioports being
   actually memory mapped on MIPS only makes the confusion worse, sigh."
